Numerous authors have reported osteolysis, case by case, which is mostly induced by noncemented arthroplasties that always gain a certain mobility by mechanical solicitation during movement. The same phenomenon may arise for craniofacial (after resection of tumors) and otologic unattached prostheses which are potentially mobilizable. 

Orthopaedic surgeons must fill defects created by trauma, removal of cancerous tumors, or abnormal development. Bone replacement and fixation are also issues for plastic surgeons in craniofacial procedures, hand and foot deformities, and extremity injuries. Though poly(methyl methacrylate) (PMMA) bone cement is currently in use to address these problems, it in nonbiodegradable, remaining in... 

Craniofacial and neck malignant tumors usually present with a highly aggressive local activity. Bone destruction and ulceration are not uncommon findings especially as a secondary effect of radiotherapy. In some cases, invasion of vascular structures may lead to a recurrent Weeding or severe hemorrhages.
